I'm finally gonna jump on this Toontrack train but I was wondering some things before I do this...which one do you guys think is more useful, SD2 or EZD2? Just all around bang for buck. I'm leaning toward Ez Drummer 2 because of the video Ola made. Also, not counting these new expansions, which one of the EZX packs would you get FIRST if you were a Toontrack virgin and wanted to do metal. I'll get them all but I wanted the best one first.
